LSD : Very trippy, plays games with your head and sometimes makes you see things that aren't there. Also, it makes everything really funny, like burst out laughing funny (even if the thing you are laughing at isn't even funny)Speed : Dirty drug, the morning after is terrible, they call it a 'come down'. Speed is basically a energy boost, has the power to keep you up all night, draining whatever energy is in your body.
